[dpdk-dev] [PATCH v2] eal/windows: fix link error with MinGW

[Tal Shnaiderman]

> Subject: [PATCH v2] eal/windows: fix link error with MinGW
> 
> Linking with the 'pci' driver when building with MinGW on Windows fails with
> undefined symbol 'GUID_DEVCLASS_NET'.
> This occurs because devguid.h is included in rte_windows.h before INITGUID
> is defined.
> 
> Move the include of devguid.h after the definition of INITGUID.
> 
> Fixes: b762221ac24f ("bus/pci: support Windows with bifurcated drivers")
